Ricky Dineen is an Irish musician best know as the founder, main music writer and guitarist with the post punk band Five Go Down To The Sea? (earlier known as Nun Attax). Dineen grew up in Curchfield, in the Cork city suburb of Gurranabraher, and in 1978 formed Nun Attax with school friends Philip and Keith O’Connell. He met their vocalist Finbarr Donnelly in 1978, when they bonded over a shared interest in UFOs. Until then Dineen had been a hard rock and Pink Floyd fan until Donnelly introduced him to post-punk and hands featured on John Peel's BBC radio show. A self-thought musician, he developed an angular guitar style influnced by bands such as The Mekons, The Fire Engines, Gang of Four and Siouxsie and the Banshees, and wrote most of the riffs for the band's songs. He currently plays guitar in Big Boy Foolish, with Liam Heffernan, and in the occasional Five Go Down To The Sea? memorial band And NUN Came Back.
